Background technology
In pelletizing or agglomerating plant, processed bulk material (for example, iron ore or zinc ore) to be filled on chassis, this chassis forms the endless chain (with reference to figure 1) also referred to as the chassis of the grid of advancing (traveling grate).Chassis is filled with bulk material and through various treating stations, in these treating stations, realizes the heat treatment of material, such as dry, fire with cooling.By lifting or drive wheel, the chassis chain is along top section (strand) through treating stations, and wherein the wheel of chassis is directed in in-orbit.In the end of top section, the heat-treatment material is being fallen wheel or the wheel of tumbling (discharge station) is dumped by gravity, and empty chassis turns back to reversedly lifting along bottom stage and takes turns thus.During transmission in top section and bottom stage, the contact between single chassis causes that necessary chain connects.Lifting and the big gear wheel of falling wheel are bonded on the pressure roll of arranged alongside on the wheel shaft of chassis of track roller, so that lifting chassis and vertically transmit chassis.
Because chassis and their parts stand high heat and mechanical wear at production period, so they are replaced after must or damaging in wearing and tearing to a certain degree.Usually, this replacing need to stop lifting wheel 5 to 10 minutes, and this may cause the other cause thermal damage of the chassis in top section.In addition, in this shutdown period, also must stop producing.After chassis is changed, pelletizing and sintering process must be adjusted to the steady production level subsequently again.This adjusting stage (in most of the cases only stopping after several turnover circulations) also has adverse effect to product design.
For fear of the above-mentioned shortcoming of discontinuous more changing device, also proposed to carry out continuous chassis and changed.The chassis that will be replaced here is removed and new chassis is inserted in idle chain position from the chassis chain.Realize this replacing during the forward space grid of being expert at operation, make the partial function of drawing and introducing need two different device locations.This more changing device by the unit of two separation, formed, the unit of these two separation is operated one by one.
In US Patent 6,523, the example of continuous replacement apparatus is described in 673.This changes Plant arrangement in lifting wheel bottom stage and lifting wheel top section.Realize removing of chassis in bottom stage.For this purpose, guide rail is opened downwards and movably on conveyer, is being drawn chassis.Conveyer is sliding stand, and the translation motion direction of this sliding stand transmits identical with the grid of advancing in bottom stage.In top section, new chassis is given rise in the grid of advancing by rotatable clamping device, wherein by the rotatable turnover panel of upwards opening, produces the insertion opening of the necessity in crooked rail.Yet, also need other lifting and conveyer to remove and insert chassis here.
Summary of the invention
Therefore, the purpose of this invention is to provide when equipment moves change chassis more simply, more reliable, safer and more cheap possibility.
This purpose is realized by the feature of claim 1 by the present invention basically, arrange and remove switch in the zone of the bottom stage of wherein taking turns in lifting, remove switch by this and can shift out chassis or analogue from chain, and in the zone of the top section of taking turns in lifting, the supply switch is set, chassis or analogue can be moved on in this chain by this supply switch.Therefore, can carry out and change and do not turn off equipment, but in minimum production speed.
By switch scheme according to the present invention, utilize the motion of chassis on himself is taken turns, make and needn't use other clamping and connecting gear, complete chassis will be arranged in this other clamping and connecting gear.Therefore also eliminate for the clamping of conventional scheme and the time of positioning function.By at lifting wheel place, chassis being given rise to top section from bottom stage, interrupt advancing the grid chain, make and do not have pressure contact during lifting between chassis.Therefore, do not need for discharging the other device of the grid chain of advancing.
According to a preferred aspect of the present invention, preferably externally remove the fixing switch that switch comprises the pressure roll that engages chassis on the inboard of rail.Due to this fixing switch, obtain the more time in order to draw and open crooked rail, because follow-up chassis still can carry out motion of translation on fixing switch, they are inserted into again by closing the outer bend guiding piece in the corresponding backlash in the lifting wheel of rotation afterwards.Here importantly, the backstage axletree is guided effectively by the lifting gear teeth.
In order to open according to exterior guiding rail of the present invention, pivotable bent connecting rod is arranged in and removes on switch, and this pivotable bent connecting rod is preferably by the actuator actuator drives.As a result, can easily open the outer link of crooked rail, make chassis to be moved out of from this equipment on fixing switch.
Because chassis does not have they self actuating device (in pelletizing or agglomerating plant, by lifting, take turns propulsive effort is provided), therefore development according to the present invention is arranged to pulling device is associated with and removes switch in order to pull out chassis.Because chassis rolls on fixing switch, therefore do not need lifting they, and simple pulling device is enough for removing.
According to the present invention, pivotable bent connecting rod also is arranged in the supply switch, in order to open the outer bend guiding piece at the top section place of lifting wheel.
According to particularly preferred aspect of the present invention, pivotable bent connecting rod forms outer bend guiding piece and the rail that is used for inserting chassis.The location of switch is realized by the motion of downward sensing, by this motion of sensing downwards, opens curved guide members in order to insert chassis simultaneously.This reduces to change required time of operation, the speed restriction of the grid of advancing that this time is moved.The action plane of regulating mechanism is parallel to the trolley movement of translation.For the collisionless process of the motion that guarantees regulating mechanism, the interior curve guiding piece is suitable for the transmission shape according to switch bent connecting rod of the present invention.

As be clearly shown that in Fig. 2 A, the direct contact between the chassis 3 of the grid 4 of advancing is taken turns 10 liftings due to chassis 3 by lifting and is separated.As a result, chassis 3 can individually be approached.Now when should remove chassis 3 from the grid 4 of advancing, by inner rotary outer bend connecting rod 16, outer bend guiding piece 9 is taken turns 10 in lifting and is opened in the zone of bottom stage 15.Fixing switch 17 is parallel to outer bend connecting rod 16 and extends, and the pressure roll 12(of chassis 3 is with reference to figure 6) move on described switch.By in bottom stage 15, proceeding motion of translation, thereby can remove chassis 3 from the grid 4 of advancing by along continuous straight runs.In fixing switch 17 back, be arranged on the guide rail 18 of extending in the development length of outside rail guiding piece, the track roller 7 of chassis 3 moves on this guide rail, makes chassis 3 easily to be shifted out (with reference to figure 2C) from the grid 4 of advancing.Due to the large weight of this chassis 3, pulling device 28 is provided for removing chassis 3(with reference to figure 7 from the grid 4 of advancing), this pulling device engages chassis 3 and by fixing switch 17 and guide rail 18, this chassis is pulled open.
By using fixing switch 17, the time of crooked rail is drawn and opens in acquisition, this is because follow-up chassis 3 temporarily can continue their motion of translation on fixing switch 17, until they are inserted into again by closing the outer bend connecting rod in the corresponding backlash 11 of lifting wheel 10.In order to guarantee clear and definite location, the backstage axletree is guided effectively by the lifting gear teeth.
Remove chassis 3 by the bottom stage 15 at lifting wheel 10, obtain gap (with reference to figure 3A) between chassis 3, this gap must be closed to form the continuous grid 4 of advancing again.In the zone of the top section 5 of lifting wheel 10, therefore new chassis 3 moves in idle lifting wheel location.This is schematically shown in Fig. 3.Externally, on curved guide members 9, pivotable bent connecting rod 20 is set, this pivotable bent connecting rod guides the chassis 3 of the grid 4 of advancing in normal running (with reference to figure 3A).In order to insert new chassis 3, bent connecting rod 20 inwardly rotates by the actuating device the following describes, so that location switch 21 is used for supplying (with reference to the figure 3B) of chassis 3.Chassis 3 can insert by supply rail 22 and bent connecting rod 20 now, makes its pressure roll 12 be bonded in the backlash 11 of lifting wheel 10 and the new chassis 3 inserted take turns 10 by lifting and continued to move.Again obtain the continuous grid 4 of advancing.The hind axle one of new chassis 3 is through switch 21, and bent connecting rod 20 just can rotate back again, in order to close exterior guiding rail 9(with reference to figure 3C).The operation of grid 4 of the advancing continuation that therefore can do as usual again.
The pressure roll 12 of changing the chassis 3 of switch 17 joints that only ought be fixed as the continuous chassis of describing with reference to figure 2 and 3 can be still possible the used time.If pressure roll 12 is damaged, they can not shift out from the grid 4 of advancing by switch 17.In this case, provide manual replacing, as with reference to the Figure 4 and 5 explanation.In the following description of this embodiment, by the difference of only discussing with chassis is changed continuously.According to the present invention, except the element for chassis is changed continuously, also be provided for the other device that discontinuous chassis is changed.
In 4C, the chassis 3 that removes damage from the grid of advancing is shown at Fig. 4 A.In Fig. 4 A, but the chassis 3 of damage is arranged in the zone of pivotable bent connecting rod 16.Owing to can not on fixing switch 17, shifting out chassis 3, chassis 3 must be maintained on its track roller 7.For this purpose, but the second pivotable bend arm 24 is set, but but but this second pivotable bend arm be longer than pivotable bent connecting rod 16 and under any circumstance be arranged to and be parallel to pivotable bent connecting rod 16 when carrying out when chassis is changed.Because space that provide by bent connecting rod 16, that be used for that chassis 3 is rotated is not enough, the second arcuate member 25 is arranged in the extension of bent connecting rod 16, and this second arcuate member can rotate and provide larger opening in opposite direction.After opening the second arcuate member 25 (Fig. 4 B), the crooked arcuate member 24 of extension is rotated down, until the front track roller 7 of chassis 3 is shelved on (with reference to figure 4C) on guide rail 18.Now, also, as in changing principle continuously, chassis 3 can be moved out of by its track roller 7 on guide rail 18.
In order to insert new chassis (with reference to figure 5), chassis 3 for example, is placed to (with reference to figure 5A) on guide rail 18 by other forwarder (, hoisting crane).By rail 18, new chassis moves to (wherein pressure roll 12 now also can engage fixing switch 17) in the clear position on the grid 4 of advancing now, and go back and close this opening by the second arcuate member 25 by crooked arcuate member 24 rotations that make to extend, therefore new chassis is inserted into (with reference to figure 5B and 5C) in the grid 4 of advancing again.Now, actuating device can be connected again, and the grid of advancing can move through balling equipment 1 in due form.
Can certainly, by this supply for continuous replacing, as shown in Figure 3, rather than supply as shown in Figure 5 new chassis 3.As a result, the cycle of closing of this equipment can further reduce, and this is because this equipment when supplying new chassis can start.
The schematically illustrated chassis 3 of Fig. 6, will only describe this chassis here briefly.Bulk material is loaded onto on grid 26 and is kept by the sidewall 27 of chassis 3.In normal running, chassis 3 moves on the rail of continuous forwarder 6 by its track roller 7.Taken turns 10 liftings by lifting or fallen wheel 13 while falling, backlash 11 and 14 engages the pressure roll 12 of the chassis 3 that is arranged in track roller 7 inboards.These pressure rolls 12 are also for transmitting chassis 3 in order to remove from the grid 4 of advancing on the switch 17 fixing.
The chassis that Fig. 7 is schematically illustrated to be comprised supply and remove layout is changing device more, and Fig. 7 A illustrates the front elevation of this device and the lateral plan that Fig. 7 B illustrates this device.
Fig. 7 B illustrates pulling device 28, and this pulling device is used for pulling out chassis 3 from the grid 4 of advancing.Yet, for the chassis by new is inserted in the top section of lifting wheel 10, thrust unit 29 is set, by this thrust unit, chassis 3 can be pulled in the grid 4 of advancing.
Next, describe in detail and be arranged in the structure that removes switch 30 on framework 36 with reference to Fig. 8.
